📗 Libro en inglés CCNA SELF-STUDY: INTERCONNECTING CISCO NETWORK DEVICES (2ND ED.)

The only authorized Self-Study guide based on the new CCNA INTRO 640-811 exam from Cisco Systems. With the introduction in June 2003 of the CCNA 640-801 and ICND 640-811 exams, Cisco Systems also introduced the newest version of the Interconnecting Cisco Network Devices (ICND) course. CCNA Self-Study: Interconnecting Cisco Network Devices (ICND), Second Edition is a Cisco authorized learning tool that helps CCNA candidates prepare for the new CCNA exams. This book is the second edition of the best-selling title for early-stage CCNA preparation (1-57870-111-2), also from Steven McQuerry. It is designed in exclusive cooperation with Cisco Systems, and it is the only title authorized by Cisco for learning of the concepts in ICND. Coverage includes a review of the OSI model, routers and switches, Cisco IOS software, command line interface, WAN, and ISND and Frame Relay. The CCNA program certifies that a professional can install, configure, and operate LAN, WAN, and dial access services for small networks (100 nodes or fewer). It is considered one of the most valuable IT certifications, and it has been growing in popularity over the last several years. hide
